I recently ran into the same issue, however I did not perform a disk resize. I noticed image backups were taking much longer to run on the 2 clients that had the issue.
Does the CBT client report to the windows event log when this occurs? If so, I can trigger an alert via my RMM tool to get someone’s attention. Is there something that could be done on the server to alert if a client that should be using CBT is not using it?
The log messages in the “CBT status” window would be helpful, as well as the volume size(s). If there is something connected with CBT in the client debug log, that would be helpful as well.
This just started sometime on 4/21-4/22. Before that CBT was working properly.
Here is CBT Status messages:
